I just clicked on "Notifications" because it was showing I had one. When the page opened a Google box was covering the left one third of the page so I could not tell if I had anything important to read. I clicked the little "X" to make it go away but all I got then was an empty box with a choice to stop seeing these Ads but clicking on that sent me right back to the original ad. It was just a cycle that wouldn't stop. I was going to go back and do screen shots, but now, when I go back to Notifications that is gone. It does leave me wondering if I missed something important---man I hate pop-up crap. Does anyone know why or how this might have happened?
